Application filed october 24, "1919.

a eitixen of the 'nited States. and a resident of New' Brunswieli. in tbe eounty of iiiddlesox and State of New Jers llave invented a new and improved Rein oreedl'onrfrete Floor (lonstrnetion, of wlliell tbe lloningj is a full. Clear, and exa't leseripnl.

'l`be objex't ol tbe invention is to provide a new and improved reinloreed eonerete lloor uonstruetion. reini'oreed*longitudinally and'tranexverxel; to render tbe floor exeeedinglv strong' and durable.

fmollier objert in to provide tlie floor with voidl tliereb)1 makin;r flul floor exeeediiufly l'iglit.

notlier objeet islo permit o 'onvenientlv and quieltlvforming tbe door without requiringr lxiglillv skilled labor.

With bese ani. other objeets in view, the invention eonsiste oi' rertain novel features olf i. tii|rtion as hereinafter shown and de.- .scribed and tlien slieeilrallv pointed out in the elainis.

n. praf-tieal embodiment ol' tbe invention is represented in tbe aeeoni|mnvingf diraningfs forming a part of this slieeiieation, in wliieli einiila eliaraetewl ol re'l'erenee indirato eorrespondiin parts in all tbe views.

Fig. 5 is a plan view of tlle floor Construction prior to applyingr tlie eeinentitious filling" material; and

Fig. 6 is a' longitudinal sectional elevation of the saine on tbe line GHG of Fig.

The bottom of the reinforced floor eonstruction is formed of slabs l() arranged in l if) 'a horizontal plane and in abutting' relation,

andthe slabs l() are supported duringr the forn'ialion of the floor by a Suitaliletemnorary Wood form. wliieh is removed after the floor if: finished. Enel; of the. slabs l() '1S preferably made of terra. cotta. ,fypsum or other oenlentitions and fireproof'material, and is provided a "the top and bottom with Specification of Letters Patent.

B V the arranger ent destribed the boxes l5 are held againnt acci*A dental shifting in a longitudinal direction.

ln order to reinforee tbe floor. use is made of transverse reinoreinp; bars 30 eaeli realt ingy on the bottoms of the stirrups 2i a. transverse row ol' .fstlrruna the smid reinoroing' bars 30 bearing on the stirrups to bold transverse reinforcing bars 30 nseiig n'lade o lonpfltudinally extending relnoreinn bara Si restingr on the transverse bars 31') and eaend ingr between longitudinal row: nl the von?.

boxes 15.

After the boxes l5 are plana-d 'X onthe slabs 10 and are eonnef-tf,M

reinforcing bars 3Q and 5U hart in posltlon as described and filling,Y ll() ot cementitious material is placed on to'p oi' the slabs l() to avdepth to embed the boxes lo, conneetino members 2l. and reinforcine bars 3() and 31. dditional rein- Jforcing- 'oars 5() may be placed in position between the longitudinal rows o'lE boxes l5 as tbe iilling is placed in position, to give additional strength to tbe ioor.

r.lie eementitious iillin ll) is placed to a desired depth lon tbe slabs il) and is molded around the under sides ot the I-beams (ll) by suitable molds, and on top of the lilling el() is placed the usual lloor f'fonstruction indicated in Fig. 1,'but as this lioor construction terms no part ot my invention it is not deemed necessary to Yfurther describe the.-

same. Aiter the temporary wood iorm or center work used for supporting the slabs has been removed then the ceiling;- plaster is applied to the under side of the slabs l() and is securely held thereon by engaging; tbe dovetail grooves ld and dovetail tongues l2. lt will be noticed tbat by having,- tbe dovetail tongues and grooves on both faces ot tbe slabs suitable keys are formed tor the cementitious material 4() and the ceiling,I pla-ster.

By the use ot tbe metallic boxes l5 voids are produced in the cementitious lilling Ll() and bence tbe floor rendered exceedingly lilexlit and a large amount of filling material is saved. As the boxes are made of metal they increase the strength o'l" thetloor,

,Having thus 'lescribed my invei'itioii, l claim as new and desire to secure by lietters Patentel.

3. A reinforced concrete floor construction, comprising slabs provided with dovetail tongues and grooves on botli faces. tbe slabs being;` arranged in a plane in abutting relation, metallic boxes, one ior leach slab, and each provided wit'n outwardly extending flanges at the bottom,J the longitudinal flanges of which extend into corresponding grooves and under corresponding tongues of the slab, and the cross flanges extend across the tongues and rest on top thereof, connectingstirrups connecting the adjacent boxes with each other, reinforcing members between the boxes, and a illing of cenientitions material on top of tlie slabs and embedding the said boxes, stirrups and reinforcing members.

4l. A' reinforced concrete floor construction, comprising slabs provided with dovetail tongues and grooves on both faces, the slabs being arranged in a plane in abutting relation, metallic boxes one 'for each `ilab and each 4provided with outwardly extending flanges at the bottom, of which the longitudinal flanges extend into corresponding; grooves and under corresponding tongues ot the slab, and the cross flanges extend across the tongues and rest on top thereof, the sides of the boxes having tlie cross Aflanges being provided near tbe top with openings, stil-rups, each having its ends extending tlnfough tbe opposite openings of adjacent boxes, the inner ends oi' the stirrups bearing,` against the under sides oi? tbe tops ot the boxes, transverse reintorciing,a rods extending' between the transverse rows of tile boxes and resting' on the said stirrups, longitudinal reintorcingl rods extending* between longitudinal rows olE the boxes, and

a fillingo'i" a cementitious material on tile top of the said slabs and filling the exposed portions ot' the grooves, the said lill` ing;` embedding` the said boxes, stirrups and reinforcing rods.
